Description
Technical field
The present invention relates to air filter field more particularly to the manufacturing methods and filtering of a kind of Partitionless air filter
Device.
Background technique
Since there is higher requirement in industrial clean place to the cleanliness of air, air purity technique is played the role of getting over
Come more important.In many air purifying process, most widely used and most mature is exactly air filter, according to different chamber's inner ring
The air cleaning requirement in border, filter are generally divided into thick effect, middle effect and efficiently.Traditional filter is mostly to have partition air filtration
Device mostly uses greatly the art paper of two-sided gluing to make demarcation plate, to prevent demarcation plate from being influenced to shrink by cold and hot dry and wet, thus
Shed fines, and when temperature and humidity changes, it is this to might have larger particles every cardboard and distribute, to cause workshop clean
Spend test failure.
Currently, having gradually appeared various non-inductive windings high efficiency particulate air filters in the market, wherein most of non-inductive windings high efficiency particulate air filter
It is all the continuous gluing on filtrate, hot melt adhesive cooled and solidified forms support after filter core folds, however this method is due to tree lace
The limited height of protuberance, the limited height of the support formed after folded filter paper, so that the ventilation quantity in the air duct between filter paper
Small, filter filter efficiency is not high, in addition, this method is since hot melt adhesive is continuously to coat, glue consumption is big, high production cost.
Therefore, the prior art still needs to improve.
Summary of the invention
The first technical problem to be solved by the present invention is how to improve the filter efficiency of air filter.
The technical proposal adopted by the invention to solve the above technical problems is that:
A kind of manufacturing method of Partitionless air filter, includes the following steps,
S10 is by hot melt adhesive heating and melting；
S20 is passed through nitrogen into hot melt adhesive in a molten state；
The hot melt adhesive that S30 is blended with nitrogen is sprayed along the length direction of filter paper, forms tree lace；
Filter paper is folded into W-shaped by S40 along its length, and makes tree lace that adjacent filter paper to be adhesively fixed, and tree lace exists
Support is formed between adjacent filter paper；
In a preferred embodiment, described to support to be formed after tree lace cooled and solidified.
In a preferred embodiment, the expansion ratio of hot melt adhesive inflated with nitrogen is not less than 40%.
In a preferred embodiment, the air pressure that is passed through of the nitrogen is not less than 126kpa.
In a preferred embodiment, the hot melt adhesive is polyolefin or ethylene-vinyl acetate copolymer (EVA).
In a preferred embodiment, the melt temperature of the polyolefin is not less than 160 DEG C, the spray of the polyolefin
It applies temperature and is not less than 135 DEG C.
In a preferred embodiment, the tree lace can be arranged a plurality of along the width direction of filter paper.
A kind of filter is made up of the manufacturing method of above-mentioned Partitionless air filter.
The beneficial effects of the present invention are:
The present invention in hot melt adhesive by being passed through nitrogen, so that hot melt adhesive is able to inflation, tree lace height increases, forms
Spacing between the filter paper of filter core afterwards becomes larger, and filter ventilation quantity becomes larger, and filter efficiency is high.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic diagram of the product of the manufacturing method of the Partitionless air filter of one embodiment of the invention；
Fig. 2 is another schematic diagram of the product of the manufacturing method of the Partitionless air filter of one embodiment of the invention
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu, complete description, to be completely understood by the purpose of the present invention, scheme and effect.It should be noted that the case where not conflicting
Under, the features in the embodiments and the embodiments of the present application can be combined with each other.
It should be noted that unless otherwise specified, when a certain feature referred to as " fixation ", " connection " are in another feature,
It can directly fix, be connected to another feature, and can also fix, be connected to another feature indirectly.In addition, this
The descriptions such as upper and lower, left and right used in invention are only the mutual alignment pass relative to each component part of the present invention in attached drawing
For system.
In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art
The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without
It is to limit the present invention.Term " and or " used herein includes the arbitrary of one or more relevant listed items
Combination.
Referring to Fig.1, Fig. 1 is one of the product of the manufacturing method of the Partitionless air filter of one embodiment of the invention
Schematic diagram, which includes filter paper 1 and tree lace 2, during the manufacturing of the product, first by granular hot melt adhesive
It is put into glue cylinder and is melted, melt temperature is selected according to the difference of the specifically used material of hot melt adhesive, the present embodiment
Hot melt adhesive selection has polyolefin, and to guarantee that polyolefin is in sticky thawing shape, melt temperature need to be not less than 160 DEG C, certainly, heat
Also ethylene-vinyl acetate copolymer (EVA) may be selected in melten gel, and melt temperature is not less than 75 DEG C.
Later, nitrogen is filled with into the hot melt adhesive of molten condition, nitrogen is passed through air pressure not less than 126kpa, to guarantee nitrogen
Gas enters in hot melt adhesive, wherein the expansion ratio of hot melt adhesive is not less than 40%, this expansion ratio can be in the support for guaranteeing tree lace 2
The height of tree lace is improved under conditions of intensity to the maximum extent, to improve the ventilation quantity of filter core.
Hot melt adhesive with nitrogen is full and uniform mix after, hot melt adhesive is coated in filter paper 1 creasy by the equipment such as glue rifle
On, form continuous tree lace 2, wherein coating direction is the length direction of filter paper 1, and tree lace 2 can be set along the width direction of filter paper 1
Set a plurality of, in the present embodiment, tree lace 2 is provided with 3, and 3 tree laces 2 are equally spaced.Finally the folding of filter paper 1 is closed up, it is cooling
Tree lace 2 bonds together adjacent filter paper 1 after solidification, and (support is solidifying by cooling down for formation support between adjacent filter paper 1
Solid tree lace formed), to form air duct.
Referring to Fig. 2, in the prior art, most of space D between the filter paper 1 of filter core between 3mm-3.8mm, by
In the limitation for the height that tree lace 2 swells, can not accomplish more greatly, to limit the ventilation quantity of filter core, to lead to non-inductive windings air mistake
The filter effect of filter can not be promoted.The Partitionless air filter made by means of the present invention, between the filter paper 1 of filter core
Space D up to 5mm-6mm, the spacing in single air duct is significantly increased, so that the ventilation quantity of integral filter core be made to be significantly increased,
The filter efficiency of Partitionless air filter greatly improves.In addition, due to the hot melt glue amount that uses of tree lace of coating unit length
Reduce, the dosage of hot melt adhesive is reduced, and can also reduce production cost while improving the filter efficiency of Partitionless air filter.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
